Equinox exhaust
i tried a carven type r muffler instead of the resonator, and removed the rear muffler under the rear hatch. unfortunately there was to much drone noise inside the cab, i thought it was because of the type of muffler but after changing the muffler back to a resonator I'm still having a lot of drone, i did run a y pipe out the rear to fill both of the exhaust exits on the muffler which may be causing this issue. let me know what you try and how it turns out
